Josef HaraldEmanuel Carlstedt, Stockholm, Sweden Application August 31, 1937-; Serial-No. 161353 In Sweden March 14, 1936 7 Claims.

My invention relates to means for preserving the shape of skis when they are not in use, especially in the warm season when they are apt to warp-out of shape, and the object of my invention is to provide a simple and cheap yet effective and universal device for said purpose.

In the accompanying drawing, Fig. 1 is an edge view of a pair of skis with the form-retaining device applied to same. Fig. 2 is a side view on an enlarged scale of the pair of skis, the middle portion of the skis being broken away. Fig; 3 is an edge view also on an enlarged scale of the'front curve of the one ski.

Referring to the drawing, l designates the skis placed with the running surfaces turned towards each other. Placed at each front curve of theski is an attachment member 2, which is preferably adjustable, so as to be capable of being moved to and attached at different places of the front curve and which may consist of a leather strap reinforced by means of a flexible steel band or the like and provided with ordinary locking means. In the embodiment shown the said strap is provided with a small slip-roller 3.

Provided transversely between the skis approximately at the root of the front curves is a slidable guide member 4 provided at its ends with small slip-rollers 5. Placed about the said latter rollers 5 as well as about the rollers 3 of the attachment members 2 is an endless cord 6, for instance a steel-wire, chain or the like. Secured to the middle point of the guide member 4 is a second cord 1, which may also consist of a steelwire, chain or the like and which, through the interconnection of links 8 and a hook 9 for varying the length of the cord, extends to the rear ends of the skis. At this end the cord 1 is connected to a screw II), which passes freely through a sleeve member ll placed between the end portions of the skis and adapted to bear against the cavettos of the skis. The sleeve II is provided with end supports 12 for the skis, which supports may be made to suit to the configuration of the ends of the skis, i. e. to straight, acute or curved ends, so as to obtain a safe support. Screwed on the screw ill outside the supports I2 is a wing-nut [3. At its inner end the screw I0 is provided with radial wings l4 adapted to enter into the cavettos of the skis, so as to prevent turning of the screw when turning the nut l3. After the nut has been screwed on, the screw can be beaten down at its outer end, so that the nut cannot be removed and get lost.

After the stretching device has been applied to the skis in the manner described, the stretchingis performed by tightening-the nut 13, whereby the running parts proper of the skis as well as the front curves will be bent and held in the desired bent form as long as the stretching device is applied. By connecting the attachment members and the guide member through an endless-cord, as shown, an equalizing of the stretching power on both of the front curves willbe attained.

If, for instance, the bending of the running parts of the skis is to be limited and that of the front curves increased, a strap I5 or any other suitable means may be applied around said parts at the usual steps, as shown in Fig. 1.

If, on the other hand, the bending of the front curves is to be limited, the attachment members Zare applied nearer the roots ofthefront curves;

If the one front curve needs to be bent more than the other, the attachment members 2 are placed at different distances from their roots.

If the one running part needs to be bent more than the other, the strap IE or the like can be applied solely around the latter running part and the cord 1, whereby the former running part obtains a greater freeness to be bent.

What I claim as new and desire to secure by Letters Patent of the United States of America 1. A ski-form protector comprising a clamping member adapted to be secured to the front curve of the ski, a movable guide member adapted to be placed transversely at or in proximity to the root of said front curve, a cord between said clamping member and said guide member, an end support adapted to bear against the rear end of the ski, a cord between the said guide member and the said end support, and power amplifying means for stretching said cords.

2. A ski-form protector comprising an adjustable clamping member adapted to be secured to the front curve of the ski, a movable member adapted to be placed transversely at or in proximity to the root of said front curve, a cord between said clamping member and said uide member, an end support adapted to bear against the rear end of the ski, a cord between the said guide member and the said end support, and power amplifying means for stretching said cords.

3. A ski-form protector for preserving the shape of a pair of skis placed with their running surfaces facing each other comprising a clamping member for each of the front curves of the skis, a movable guide member adapted to be placed transversely between the skis at or in proximity to the root of said front curves, an endless cord slidably connected to said clamping members and to the ends of said transverse guide member, an end support adapted to bear against the rear ends of the skis, a cord between the said guide member and the said end support, and power amplifying means for stretching said cords.

4. A ski-form protector for preserving the shape of a pair of skis placed with their running surfaces facing each other comprising an adjustable clamping member for each of the front curves of the skis, a movable guide member adapted to be placed transversely between the skis at or in proximity to the root of said front curves, an endless cord slidably connected to said clamping members and to the ends of said transverse guide member, an end support adapted to bear against the rear ends of the skis, a cord between the said guide member and the said end support, and power amplifying means for stretching said cords.

5. A ski-form-protector for preserving the shape of a pair of skis placed with their running surfaces facing each other comprising a clamping member for each of the front curves of the skis, a movable guide member adapted to be placed transversely between the skis at or in proximity to the root of said front curves, a sliproller at each of said clamping members, a sliproller at each end of said transverse guide member, an endless cord placed around all of said slip-rollers, an end support adapted to bear against the rear ends of the skis, a cord between the said guide member and the said end support, and power amplifying means for stretching said cords.

6. A ski-form protector for preserving the shape of a pair of skis placed with their running surfaces facing each other comprising a clamp ing member for each of the front curves of the skis, a movable guide member adapted to be placed transversely between the skis at or in proximity to the root of said front curves, an endless cord slidably connected to said clamping members and to the ends of said transverse guide member, an end support adapted to bear against the rear ends of the skis, a cord between the said guide member and the said end support, and means for stretching said cords, said means comprising a screw running freely through said end support in the longitudinal direction of the skis and having its inner end connected to said latter cord and a nut at its outer end outside said end support.

'7. A ski-form protector for preserving the shape of a pair of skis placed with their running surfaces facing each other comprising a clamping member for each of the front curves of the skis, a movable guide member adapted to be placed transversely between the skis at or in proximity to the root of said front curves, an endless cord slidably connected to said clamping members and to the ends of said transverse guide member, an

end support adapted to bear against the rear ends of the skis, a cord between the said guide members and the said end support, and means for stretching said cords, said means comprising a screw running freely through said end support in the longitudinal direction of the skis and having its inner end connected to said latter cord and a nut at its outer end outside said end support and having further radial projections at its inner end adapted to bear against the skis, so as to prevent turning of the screw at the turning of the nut.
